We describe an experimental system to study nucleocytoplasmic diffusion of proteins in living HeLa cells. To localize proteins to the nucleus, substrates were created that contain a nuclear localization sequence fused to Aequorea victoria green fluorescent protein (GFP). Transiently and stably transfected HeLa cells were used for these assays. A protein of 29-kDa molecular mass that harbors GFP and the bipartite Xenopus nucleoplasmin nuclear localization sequence (NLS) accumulates efficiently… CONTINUE READING
